Lock-up control solenoid valves are activated in accordance with lock-up condition. See LOCK-UP CONTROL SOLENOID VALVE OPERATION  table. Lock-up control solenoid valve assembly is located on transaxle. See Figure . Lock-up control solenoid valve "A" has a Yellow wire and solenoid valve "B" has a Green/Black wire.
